TOPIC: SmoothZoom Glitching In 2:1 Aspect Ratio Timeline?

So I've been trying to get various SmoothZoom type effects to work properly in a 4K 2:1 aspect ratio timeline, but it seems to be kind of glitching/squeezing the effect in the 2:1 "box" instead of just cropping the 16x9 video clips in the 2:1 frame...I want to do this as I just like the 2:1 aspect ratio.

The video files are in UHD 4K, and I set the timeline resolution to 3840x1920 and it looks great, except for these SmoothZoom transitions...As you can see it gives a kind of caliedescope effect and then once the playhead goes off the transition it snaps back to "normal" looking...whereas with a 16x9 timeline it doesn't make this glitch on the edges and there is no "snap" back to normal at the end of the transition.

Last frame of the SmoothZoom transition:

I've tried different versions of the smooth zoom effect and also tried different Spacial Conform settings, etc...Any ideas on how to get this to work aside from just changing back to the standard 16x9 aspect ratio? Or a specific SmoothZoome type effect that will not get weird with different aspect ratios?

Your first pic has a MIRROR effect at the ends (guy butting his own head, door double hinges) whereas the 2nd pic is normal. What's with that? Methinks you've left an effect on by accident as the two frames don't jive.

If it's the smooth zoom transitions from sellfy.com, it looks like they didn't add any snapshots for any other aspect ratios other than 16:9. You can open the transition in Motion and add the missing snapshot in the project settings > snapshots and then tweak the position of the placeholders to line up properly.
